National flag

Flag	Date	Use	Description
	In use since 1822, and from 1978 onwards as the sole National Flag.	The current Flag of Greece was adopted by the First National Assembly at Epidaurus in January 1822 as the official naval ensign of the country. Between 1822 and 1978, this flag was flown on Greek vessels and also used for foreign service. In 1978, it was established as the sole National Flag of Greece, and as the war and civil Ensign, and has been used in that capacity ever since.	Nine horizontal stripes of equal width; five blue alternating with four white. Number nine stands for the syllables of the National Motto of Greece. Blue canton of square shape, five stripes wide, bearing a white Greek cross at its center, with the arms of the cross being one stripe wide. Canton and stripe elements combined properly, in a harmonious and complementary fashion. Flag ratio is 2:3 and color shade is traditionally intermediate, neither light, nor dark, although its precise shade is not officially stipulated by law.
	Same as above. Particular shade of blue introduced in 1970.	Same as above.	Variant of the Greek National Flag in 2:3 aspect ratio and in a "midnight blue" shade. Although legally valid and fully equivalent to the version depicted above, flag variants in darker shades of blue are reminiscent of the flag used between 1970 and 1975 as introduced by the Regime of the Colonels, albeit in a 7:12 rather than a 2:3 aspect ratio for the duration of that time period.
